We divide 408435 by 57
The aim is to understand the frequency of 57 in 408435.

Let's proceed to step 1:
The number 57 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 57

Advancing to step 2:
57 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 57

Moving on to step 3:
57 can be fit into 408 7 times, resulting in a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 399 from 408 leaves us with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 57

Let's proceed to step 4:
The number 57 fits into 94 1 times, leaving a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
The remainder is 37 after subtracting 57 from 94.
Fetch the next digit (3) from the dividend, attach it to 37 and continue: 373 / 57

Going ahead to step 5:
The number 57 fits into 373 6 times, leaving a remainder of 31.
Use 6 as the next digit of our solution. 
Result so far: 716.0
The remainder is 31 after subtracting 342 from 373.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 57

Step 6:
If we divide 315 by 57, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 7165.0
If we subtract 285 from 315, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
57 goes into 300 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 7165.5
Subtracting 285 from 300 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
57 can be fit into 150 2 times, resulting in a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 7165.52
If we take 114 away from 150, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
360 divided by 57 is 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 7165.526
Subtract 342 from 360 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
57 can be fit into 180 3 times, resulting in a remainder of 9.
The next digit of our result is 3. 
Result so far: 7165.5263
Subtract 171 from 180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 11:
When dividing 90 by 57, we get 1 with a remainder of 33.
The next digit of our result is 1. 
Result so far: 7165.52631
If we take 57 away from 90, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 12:
330 divided by 57 is 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 7165.526315
If we take 285 away from 330, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 13:
57 goes into 450 7 times with a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 7165.5263157
Subtract 399 from 450 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 14:
57 can be fit into 510 8 times, resulting in a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 7165.52631578
Subtract 456 from 510 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Our division results in 7165.52631578 with a remaining 5.4e-08.
